 Topic: Using CXTPReportRows::ReserveSizePosted: 29 September 2007 at 2:58pm |

Hello,
I see that a new optimization method, CXTPReportRows::ReserveSize, has been added to the report control for the 11.2 release. Could someone provide "best practices" for how this should be used? In our case, we add records to the control on the fly, then call Populate(). So my assumption is that I should call ReserveSize(N) right before I call Populate() - where N is the number of records added in previous steps. This is correct usage, or is there a better way? P.S. - I am not using virtual mode. |

Hi,
If you use a significant number of records with your Report control, you can simply enable new optimization features:
Some methods like CXTPReportRows::ReserveSize, related to recently added optimization bunch, are public and you can use them if feel helpful. CXTPReportRows::ReserveSize works similar to CArray::SetSize -- it prevents adding elements to your array with frequently memory reallocation (which then causes memory fragmentation). -- WBR, Serge |
